Two pieces of an aircraft that have been recovered in Mozambique likely belong to the Malaysian Airlines flight MH370 which went missing from radar screens two years ago, Australian authorities said.

“The analysis has concluded the debris is almost certainly from MH370,” Australia’s Federal Transport Minister Darren Chester said. “That such debris has been found on the east coast of Africa is consistent with drift modeling... and further affirms our search efforts in the southern Indian Ocean.”

The first piece was found by Liam Lotter, 18, in the city of Xai-Xai, Mozambique, on December 30, investigators said earlier in March.

Malaysian Airlines flight MH370 vanished with 227 passengers and 12 crew members onboard in March 2014, during a flight from Kuala Lumpur to Beijing. The plane disappeared from radar screens shortly after takeoff. The crash site of the plane has not been found, but the search operation continues.

Meanwhile, relatives of the passengers on the plane say that Malaysian authorities haven’t given any substantial explanation about the flight’s disappearance.

On February 25, more than 200 angry relatives held staff members of the airline in a hotel ballroom in Beijing, where a briefing was due to take place, for over than 10 hours. More than 100 police and paramilitary officers were deployed before the group finally released the staff members.
